- MUONCheckMisAligner:
-
- This macro performs the misalignment on an existing muon arm geometry
- based on the standard definition of the detector elements in
- $ALICE_ROOT/MUON/data
-
- It uses AliMUONGeometryAligner :
- --> creates a new AliMUONGeometryTransformer and AliMUONGeometryAligner
- --> reads the transformations in from the transform.dat file (make sure that
- this file is the _standard_ one by comparing it to the one in CVS)
- --> creates a second AliMUONGeometryTransformer by misaligning the existing
- one using AliMUONAligner::MisAlign
- --> User has to specify the magnitude of the alignments, in the Cartesian
- co-ordiantes (which are used to apply translation misalignments) and in the
- spherical co-ordinates (which are used to apply angular displacements)
- --> User can also set misalignment ranges by hand using the methods :
- SetMaxCartMisAlig, SetMaxAngMisAlig, SetXYAngMisAligFactor
- (last method takes account of the fact that the misalingment is greatest in
- the XY plane, since the detection elements are fixed to a support structure
- in this plane. Misalignments in the XZ and YZ plane will be very small
- compared to those in the XY plane, which are small already - of the order
- of microns)
- Note : If the detection elements are allowed to be misaligned in all
- directions, this has consequences for the alignment algorithm, which
- needs to know the number of free parameters. Eric only allowed 3 :
- x,y,theta_xy, but in principle z and the other two angles are alignable
- as well.

+/// \brief This macro performs the misalignment on an existing muon arm geometry
+///
+/// This macro performs the misalignment on an existing muon arm geometry
+/// based on the standard definition of the detector elements in
+/// the AliMUONGeometryTransformer class.
+///
+/// It uses AliMUONGeometryMisAligner :
+/// - Creates a new AliMUONGeometryTransformer and AliMUONGeometryMisAligner
+/// - Loads the geometry from the specified geometry file (default is geometry.root)
+/// - Creates a second AliMUONGeometryTransformer by misaligning the existing
+/// one using AliMUONGeometryMisAligner::MisAlign
+/// - User has to specify the magnitude of the alignments, in the Cartesian
+/// co-ordiantes (which are used to apply translation misalignments) and in the
+/// spherical co-ordinates (which are used to apply angular displacements)
+/// - User can also set misalignment ranges by hand using the methods :
+/// SetMaxCartMisAlig, SetMaxAngMisAlig, SetXYAngMisAligFactor
+/// (last method takes account of the fact that the misalingment is greatest in
+/// the XY plane, since the detection elements are fixed to a support structure
+/// in this plane. Misalignments in the XZ and YZ plane will be very small
+/// compared to those in the XY plane, which are small already - of the order
+/// of microns)
+/// - Default behavior generates a "residual" misalignment using gaussian
+/// distributions. Uniform distributions can still be used, see
+/// AliMUONGeometryMisAligner.
+/// - User can also generate module misalignments using SetModuleCartMisAlig
+/// and SetModuleAngMisAlig
+///
+/// Note: If the detection elements are allowed to be misaligned in all
+/// directions, this has consequences for the alignment algorithm, which
+/// needs to know the number of free parameters. Eric only allowed 3 :
+/// x,y,theta_xy, but in principle z and the other two angles are alignable
+/// as well.
